Apple just made upgrading to an iPhone 7 a philanthropic decision by adding a red special edition to the lineup. The new red aluminum finish, which is available to order for both iPhone 7 and 7 Plus in-store and online on March 24, is a fundraising effort for the Global Fund. Apple will contribute a portion of red iPhone sales to the fight against AIDS and HIV.

The two new red iPhones will come in 128GB and 256GB storage variations and start at $749 in the U.S. Apple will sell the special editions in more than 40 countries by the end of March, with Brazil, Chile, Colombia, India, and Turkey to come in April. If you live in the U.S., U.K., or China and are part of the iPhone Upgrade Program, you’ll be able to snag an unlocked red iPhone with AppleCare+. In the U.S., the 128GB iPhone 7 will start at $37 a month with the ability to upgrade every year.

Apple has a long-standing relationship with the Global Fund and has a variety of products in its red lineup, including iPods, cases, headphones, and speakers. Last December, Apple celebrated its decade-long partnership with the Global Fund by donating proceeds from in-app purchases, exclusive downloads, and newly launched accessories to the nonprofit. The company has so far donated more than $130 million to the Global Fund, making it the organizations’s largest corporate donor.

iPhone SE gets a bump, too

Apple hasn’t forgotten about the littlest phone in its lineup, the iPhone SE. The company just doubled the 4-inch phone’s storage to 32GB and 128GB, up from 16GB and 64GB. Those models will be phased out and the roomier new options will start at $399 beginning March 24.

While the flashy new color and iPhone SE upgrade aren’t the biggest iPhone news of the year—that will come in September with the 10th anniversary iPhone 8—it’s nice to see Apple add a little something extra to both its existing flagship and its entry-level phones.
